Hi, I do not have any information or hardware about PPC. Should it own
something like OpenFirmware? In this case it is possible to read clock
information from this.

On some models, yes, on some no. Older machines have a firmware that
won't tell you anything, the MacOS driver back then was hard coding the
values.

Anyway, the clocks are ok, apparently (maybe not the engine one though,
see later), the problem was that the DLL magic was reverted for the
LT-G, plus some minor issues with the driver blowing up on non-BIOS
machines that I can fix.

The engine tends to lockup quickly though, I'll do experiments.

I found, that we change a little behaviour. Please give a try for this
patch...

Your patch seem to address the DLL issue, I did that too, fixes the
display, I'll toy around and let you know.

Also, when just dropping the existing driver into the current linus tree,
the cursor code is blowing up, I don't know why yet, I suppose some changes
to the common code in the fbdev tree. I'll have a look.

I really want this new driver to be sent upstream ASAP. What I may do is
once I get it working well enough, I'll send it to andrew for the -mm tree
and leave it there for a while to get it properly tested.

Hi, here a snapshot from my tree over 2.6.7 + js3

Changes:

revert SDRAM_MAGIC_PLL to old behaviour
do a "from BIOS" initialisation only by __i386__
